Description

Technical Field

[0001] The utility model belongs to the technical field of compressor bearing adjustment, and particularly relates to a movable bearing adjustment device for a compressor. Background Technique

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and is known as the heart of a refrigeration system. Its main function is to circulate the refrigerant in the system by raising the gas pressure, realizing the endothermic and exothermic processes, and achieving the purpose of temperature regulation. When installing the bearings, two or more bearings need to be adjusted so that the bearings can reach a coaxial state.

[0003] The existing bearing adjustment devices are usually adjusted during the installation process and do not have the adjustment function after installation. With the long-term use of the compressor, the bearings will shift. The long-term accumulation will cause a large shift, which not only affects the rotation of the rotating shaft, but also easily causes the rotating shaft to be distorted and even broken when it is serious, resulting in economic losses. Therefore, we propose a movable bearing adjustment device for a compressor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a movable bearing adjustment device for a compressor. By setting an adjustment component, specifically, using a hex wrench to drive the rotation of bolt one, bolt one will drive the bearing mounting block to move downward or upward to adjust the height position. By using a hex wrench to drive the rotation of bolt two, bolt two will smoothly drive the moving seat to move left or right under the action of the second limiting ring to adjust the left and right positions of the bearing mounting block. This adjustment device can also perform fine adjustment after installation, so as to control the rotating shaft to always be at the coaxial position, reduce the occurrence of distortion, improve the service life, and solve the problem that the existing compressor bearings do not have the adjustment function after installation. With the long-term use of the compressor, the bearings will shift. The long-term accumulation will cause a large shift, which not only affects the rotation of the rotating shaft, but also easily causes the rotating shaft to be distorted and even broken when it is serious.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a movable bearing adjustment device for a compressor, including a compressor main body. A power seat is arranged on the back of the compressor main body, and an adjustment component is arranged on the front of the compressor main body. The adjustment component includes an adjustment seat, the back of the adjustment seat is fixedly connected to the front of the power seat, and a rotating shaft is arranged inside the compressor main body;

[0007] A bearing mounting block is provided inside the adjustment base. A moving block is arranged above the bearing mounting block. A threaded hole is formed inside the moving block, and a first bolt is threadedly connected to the inner wall of the threaded hole. A moving seat is arranged below the bearing mounting block. A second bolt is arranged on the right side of the moving seat. The right side of the second bolt penetrates through the adjustment base and extends to the outside. The outer surface of the second bolt is threadedly connected to the right side of the adjustment base. By providing an adjustment component, specifically, a hex wrench is used to drive the first bolt to rotate, then the first bolt will drive the bearing mounting block to move downward or upward to adjust the height position. By driving the second bolt to rotate with a hex wrench, the second bolt will smoothly drive the moving seat to move left or right under the action of the second limiting ring to adjust the left and right positions of the bearing mounting block. This adjustment device can also perform fine adjustment after installation, so as to control the rotating shaft to always be at the coaxial position, reduce the occurrence of twisting, and improve the service life.

[0008] Furthermore, a bearing is inserted into the bearing mounting block. An inner rod is fixedly connected to the bottom of the adjustment base.

By the moving block following the bearing mounting block to move together, both the left and right positions and the up and down height positions can be adjusted, achieving the effect of non-interference and making the adjustment more flexible.

[0009] Furthermore, two limiting rods are fixedly connected to the right side of the moving seat. The right sides of the two limiting rods both penetrate through the adjustment base and extend to the outside. The limiting rods are slidably connected to the adjustment base. When the moving seat moves, the limiting rods move together and slide on the adjustment base, improving the stability of the moving seat during movement.

[0010] Furthermore, a second limiting ring is fixedly connected to the center of the right side of the moving seat. A T-shaped groove is formed in the bottom of the moving seat. A T-shaped sliding rail is fixedly connected to the bottom inner wall of the adjustment base. The outer surface of the T-shaped sliding rail is in contact with the inner wall of the T-shaped groove. Two limiting frames are fixedly connected to the top inner wall of the adjustment base. The bottom of the moving block is in contact with the inner wall of the limiting frame. The bearing mounting block will drive the moving block to slide in the sliding groove, and the moving block slides on the limiting frame, which not only improves the supporting effect but also enables the bearing mounting block and the moving block to move more stably.

[0011] Furthermore, the bottom of the moving seat contacts the bottom inner wall of the adjusting seat. The bottoms of both limiting plates are fixedly connected to the top of the bearing mounting block.

When the bearing mounting block moves upward or downward, the limiting plate will slide on the moving block, which plays a role in limiting the bearing mounting block, enabling the bearing mounting block to move linearly upward or downward, thereby avoiding the offset of the bearing mounting block and improving the adjustment accuracy.

[0012] The utility model has the following beneficial effects:

[0013] By setting an adjustment component, specifically using a hex wrench to drive the first bolt to rotate, the first bolt will drive the bearing mounting block to move downward or upward to adjust the height position. By using a hex wrench to drive the second bolt to rotate, the second bolt will smoothly drive the moving seat to move to the left or right under the action of the second limiting ring to adjust the left and right positions of the bearing mounting block.

[0025] Please refer to Figures 1-5As shown in the figure, the utility model relates to an adjustable device for the movable bearing of a compressor, which comprises a compressor main body 1. A power seat 11 is arranged on the back surface of the compressor main body 1, and an adjustment component 12 is arranged on the front surface of the compressor main body 1. The adjustment component 12 comprises an adjustment seat 121. The back surface of the adjustment seat 121 is fixedly connected with the front surface of the power seat 11. A rotating shaft 13 is arranged inside the compressor main body 1. An inner bearing installation block 122 is arranged inside the adjustment seat 121. A moving block 123 is arranged above the inner bearing installation block 122. A threaded hole is formed inside the moving block 123, and a first bolt 231 is in threaded connection with the inner wall of the threaded hole. A moving seat 124 is arranged below the inner bearing installation block 122. A second bolt 241 is arranged on the right side of the moving seat 124. The right side of the second bolt 241 penetrates through the adjustment seat 121 and extends to the outside. The outer surface of the second bolt 241 is in threaded connection with the right side of the adjustment seat 121. By arranging the adjustment component 12, specifically, using a hexagon wrench to drive the first bolt 231 to rotate, the first bolt 231 will drive the inner bearing installation block 122 to move downward or upward to adjust the height position. By driving the second bolt 241 to rotate with a hexagon wrench, the second bolt 241 will smoothly drive the moving seat 124 to move to the left or right under the action of a second limiting ring 243 to adjust the left and right positions of the inner bearing installation block 122. This adjustment device can also perform fine adjustment after installation, so as to control the rotating shaft 13 to always be in the coaxial position, reduce the occurrence of distortion, and improve the service life. A bearing 221 is inserted into the inner bearing installation block 122. An inner rod 222 is fixedly connected to the bottom of the adjustment seat 121. An outer rod 223 is slidably connected to the outer side of the inner rod 222. The bottom of the outer rod 223 is fixedly connected to the top of the moving seat 124. The left and right sides of the moving block 123 are both in contact with limiting plates 233. A sliding groove 125 is formed in the top of the adjustment seat 121. The outer side of the moving block 123 is slidably connected to the inner wall of the sliding groove 125. A first limiting ring 232 is fixedly connected to the center of the top of the inner bearing installation block 122. The top of the first limiting ring 232 is rotatably connected to the bottom of the first bolt 231. By arranging the inner rod 222 and the outer rod 223, specifically, when the moving seat 124 moves, it will drive the inner bearing installation block 122 to move through the outer rod 223 and the inner rod 222. At the same time, the inner bearing installation block 122 will drive the moving block 123 to slide in the sliding groove 125. By the moving block 123 moving together with the inner bearing installation block 122, it can not only adjust the left and right positions but also adjust the up and down height positions, achieving the effect of non-interference and making the adjustment more flexible.

The bearing mounting block 122 drives the moving block 123 to slide in the chute 125, and the moving block 123 slides on the limit frame 15, which not only improves the support effect but also enables the bearing mounting block 122 and the moving block 123 to move more stably. The bottom of the moving seat 124 contacts the bottom of the inner wall of the adjusting seat 121. The bottoms of the two limit plates 233 are fixedly connected to the top of the bearing mounting block 122. The left side of the bolt two 241 is rotatably connected to the right side of the limit ring two 243. The inner ring of the bearing 221 is sleeved on the outer side of the rotating shaft 13. When the bearing mounting block 122 moves upward or downward, the limit plate 233 slides on the moving block 123 to play a limiting role on the bearing mounting block 122, so that the bearing mounting block 122 moves linearly upward or downward, thereby avoiding the situation of deviation of the bearing mounting block 122 and improving the adjustment accuracy.

At the same time, the limiting plate 233 will slide on the moving block 123 to limit the bearing mounting block 122, enabling the bearing mounting block 122 to move linearly upward or downward, thereby avoiding the situation of offset of the bearing mounting block 122 and improving the adjustment accuracy. At the same time, when the bearing mounting block 122 adjusts its height, it will drive the inner rod 222 to slide inside the outer rod 223. Through the two, the bearing mounting block 122 can be connected to the moving seat 124. Subsequently, by using a hex wrench to drive the rotation of the second bolt 241, the second bolt 241 will smoothly drive the moving seat 124 to move to the left or right under the action of the second limiting ring 243. The moving seat 124 will slide on the T-shaped slide rail 14. At the same time, the limiting rod 242 will move together and slide on the adjusting seat 121 to improve the stability of the moving seat 124 during movement. The moving seat 124 will drive the bearing mounting block 122 to move through the outer rod 223 and the inner rod 222 to adjust the left and right positions. At the same time, the bearing mounting block 122 will drive the moving block 123 to slide in the chute 125, and the moving block 123 will slide on the limiting frame 15, which not only improves the supporting effect but also enables the bearing mounting block 122 and the moving block 123 to move more stably. And the moving block 123 moves together with the bearing mounting block 122, which can adjust both the left and right positions and the up and down height positions, achieving the effect of non-interference and making the adjustment more flexible.
